Intel NUC Kit <BXNUC9I7QNX> - annoying sound from the power supply

[Stratege]

Hello,

I broth new Intel NUC Kit <BXNUC9I7QNX>. Installed SSD and Memory to it. As soon as I turn power on it, I can hear annoying ringing/squeaking sound from the power supply. From its rear part where cable exit to unit. Sound stops from time to time, but then again starts.

Is it usual for them to have such sound? I ask it because it is already second unit, I returned 1st one to store with same problem, but new one has same annoying sound, so I want to understand it is okey, or I should also return this unit to store. Or maybe there is some setting it bios that can fix it.

What do you mean by the power supply?  Do you mean the transformer on the cord?

I mean power supply, BXNUC9I7QNX have internal FLEX ATX power supply.
